5. be equipped with separation frame in the cavity of crane span structure ontology two, convenient for the classification cabling between cable, and due to cable it
Between separated arrangement, reduce cable between interact caused by due to heat production；
6. separation frame is netted, the heat that cable produces is made greatly to distribute while support cable；
7. using snap fit between the first slideway and the first slide bar and between the second slide bar and the second slideway, make bridge
Frame in process of deployment, between slideway and slide bar without departing from；
8. separation frame is not provided in the cavity of crane span structure ontology one, the weight of crane span structure entirety can be reduced and can be reduced into
This；
9. the separation frame in crane span structure ontology two can set it is multigroup, make crane span structure have better applicability；
